Pace-aware music player
An electronic device may comprise audio processing circuitry, pace tracking circuitry, and positioning circuitry. The pace tracking circuitry may be operable to selects a tempo of songs for playback, by the audio processing circuitry based on position data generated by the positioning circuitry, a desired tempo, and whether the songs are stored locally or network-accessible. The position data may indicate the pace of a runner during a preceding, determined time interval. The pace tracking circuitry may control the song selection and/or time stretching based on a runner profile data stored in memory of the music device. The profile data may include runner's distance-per-stride data. The electronic device may include sensors operable to function as a pedometer. The pace tracking circuitry may update the distance-per-stride data based on the position data and based on data output by the one or more sensors.
1. A system comprising:
an electronic device comprising audio processing circuitry and pace tracking circuitry, wherein:
said pace tracking circuitry is operable to process one or more songs for playback by said audio processing circuitry; and
said pace tracking circuitry selects a tempo for playback of said one or more songs without affecting pitch of said one or more songs, wherein said tempo is selected based on a desired pace and whether said songs are stored locally in said electronic device such that network-accessible songs are selected with a tempo faster than said selected tempo for playback and locally stored songs are selected with a tempo above, equal to, or slower than said tempo for playback.
2. The system of claim 1 , wherein said electronic device comprises positioning circuitry that determines position data for determining a pace of a runner during a preceding, determined time interval.
3. The system of claim 2 , wherein:

6. The system of claim 2 , wherein:
said pace tracking circuitry controls tempo adjusting based on position data generated by said positioning circuitry with respect to a desired position.
7. The system of claim 6 , wherein said position data indicates pace of a runner during a preceding, determined time interval.
8. The system of claim 6 , wherein:
said electronic device comprises memory, and:
said pace tracking circuitry selects said tempo based on runner profile data stored in said memory.
9. The system of claim 8 , wherein said profile data comprises distance-per-stride data.
10. The system of claim 9 , wherein:
said electronic device comprises one or more sensors operable to function as a pedometer; and
said pace tracking circuitry is operable to update said distance-per-stride data based on said position data and based on data output by said one or more sensors.
11. A method comprising:
in an electronic device comprising audio processing circuitry and pace tracking circuitry:
processing, by said pace tracking circuitry, one or more songs for playback by said audio processing circuitry; and
selecting, by said pace tracking circuitry, a tempo for playback of said one or more songs without affecting pitch of said one or more songs, wherein said tempo is selected based on a desired pace and whether said songs are stored locally in said electronic device such that network-accessible songs are selected with a tempo faster than a desired tempo for playback and locally stored songs are selected with a tempo above, equal to, or slower than said tempo for playback.
12. The method of claim 11 , wherein said electronic device comprises positioning circuitry that determines position data for determining a pace of a runner during a preceding, determined time interval.
13. The method of claim 12 , wherein said electronic device comprises memory, and the method comprises:
said pace tracking circuitry selecting said tempo based on runner profile data stored in said memory.
14. The method of claim 13 , wherein said profile data comprises distance-per-stride data.
